Adriana opened a savings account and deposited $300.00 as principal. The account earns 6% interest, compounded annually. What is the balance after 9 years? Use the formula A=P1+ r n nt, where A is the balance (final amount), P is the principal (starting amount), r is the interest rate expressed as a decimal, n is the number of times per year that the interest is compounded, and t is the time in years. Round your answer to the nearest cent.
Answer:
$506.7
Step-by-step explanation:
Step one:
given
Principal = $300
rate= 6% = 0.06
time = 9 years
Required
The final amount A
Step two:
The compound interest formula is
[tex]A= P(1+r)^t\\\\A= P(1+0.06)^9\\\\A= 300(1+0.06)^9\\\\A= 300(1.06)^9\\\\A= 300*1.689\\\\A=506.7[/tex]
Work the value if each expression when a=2, b = -3, c=4 and d= -5.

h) bc/a d
*Sorry its so long, I need to understand it for class.*
The solutions to each of the given algebraic expressions when a=2, b = -3, c=4 and d= -5a are as follows;
a) a + 2b = -4
b) bd - 10 = -25
c) 4b + 2a = -8
d) ab + cd = -26
e) cd² + ab = 94
f) d/2 - a = -9/2
g) bc/ad = 6/5
What is the solution to the algebraic expressions?We are given the values a = 2, b = -3, c = 4 and d = -5.
a) a + 2b
Plug in 2 for a and -3 for b to get;
2 + 2(-3) = -4
b) bd - 10
Plug in b = -3 and d = -5 to get;
(-3 * -5) - 10 = -25
c) 4b + 2a
Plug in a = 2, b = -3 to get;
4(-3) + 2(2) = -12 + 4 = -8
d) ab + cd
Plug in a = 2, b = -3, c = 4, d= -5 to get;
(2 * -3) + (4 * -5) = -26
e) cd² + ab
Plug in a = 2, b = -3, c = 4, d= -5 to get;
(4 * (-5)²) + (2 * -3) = 94
f) d/2 - a
Plug in a=2 and d= -5 to get;
(-5/2) - 2 = -9/2
g) bc/ad
Plug in a=2, b = -3, c=4 and d= -5 to get;
(-3 * 4)/(2 * -5) = 12/10 = 6/5

It is estimated that the chloride concentration will change −2115 mg/L the next year. What is the total change that will likely occur in 2 years?
Complete question :
Each year, the Department of Water Works measures the chloride concentration level in the water. The first year, they found the chloride concentration changed by −1 3/5 mg/L . It is estimated that the chloride concentration will change −2 1 /15 mg/L the next year. What is the total change that will likely occur in 2 years?
Answer:
- 3 2/3 mg/L
Step-by-step explanation:
Given that:
Change in concentration during first year = - 1 3/5 mg/L
Estimated change in second year = - 2 1/15 mg/L
Total change in concentration likely to occur over the 2 years:
This will be the sum of the concentration in the first and second year:
[-1 3/5 + (-2 1/15)] mg/L
-1 3/5 - 2 1 /15
-8 / 5 - 31 /15
L. C. M of 5 and 15 = 15
(-24 - 31) / 15
= - 55 / 15
= - 3 10/15
= - 3 2/3 mg/L

A sales associate in a store earns $325 per week, plus a commission equal to 4% of her sales. This week, her goal is to earn at least $475. At least how many dollars worth of sales does she need to make in order to hit her goal. (Hint: 4%=0.04)
Answer: She will need to sell at least ($3,750) of merchandise in order to reach her goal of $475 in one week.
Step-by-step explanation:
It is GIVEN that she earns a weekly salary of $325 and she needs $475.
Subtract $325 from $475 (425-325)=150.
Now we know that she needs $150 to earn on top of her salary to reach her goal of $475.
I used a calculator to plug in (x)0.04=150
I received 3750 as my answer
$3750 times 4%= 150

A bag is filled with 100 marbles that are all the same size and shape each marble has one color the number of marbles in a colors are listed below 21 green 35 blue 18 red 26 yellow one marble is randomly selected from the bag which word best describes the probability of it being green
Answer: 21/100
Step-by-step explanation:
Number of green marbles = 21
Number of blue marbles = 35
Number of red marbles = 18
Number of yellow marbles = 26
Total number of marbles = 100
The probability of choosing a free marble will be:
= Number of green marbles / Tot number of marbles
= 21 / 100

in graphing what would be x and y? 0.2(1)=0.5(1-6)
In graphing x is the value on the x axis and y is the values that represent values on y axis.
Given nothing but we are required to tell what x symbolises and y symbolises in graphing.
A graph is basically a common data structure that consists of a finite set of nodes and a set of edges connecting them.
There are coordinates which are written as (x,y) where x symbolises the values on x axis and y represents the values on y axis.
Suppose the coordinate is (2,3). In this we have to plot a point equal to x=2 and then a point equal to 3.Now take one line from both the points straight and the point where they meet will be (2,3).
Hence in graphing x is the value on the x axis and y is the values that represent values on y axis.

of a random variable What proportion of the values in the population does
not ie between the two zscores indicated on the diagram?
OA 02881
OB. 0.3102
OC. 03064
OD. 0.3175
OE 0.2933
Answer:
D
Step-by-step explanation:
Here, we want to get the proportion that lies outside the given shown z-scores
Mathematically, that will be:
1 - proportion lying between the two z-scores
The probability lying between the two z-scores can be calculated using the normal distribution table
That will be;
P(-1.25 < x < 0.80)
From the table, this is;
0.68249
So the proportion lying outside will be;
1-0.68249 = 0.31751
This is approximately 0.3175

I’m very confused -_-
Answer:
It's C
Step-by-step explanation:
A car dealer is calculating the list price for a used car. The dealer takes the initial price of the car and adds $259 dollars for cleaning and shipping the car to the dealer. The dealer then increases that price by 25% for the dealer’s profit. That price is then increased again by 10% for the salesperson’s commission. If a used car is initially priced $10,000, what will be the list price for this car?
Add the 259 to the initial price:
10,000 + 259 = 10,259
Increase that price by 25%, so multiply by 1.25:
10259 x 1.25 = 12,823.75
The price is then increased by another 10%, multiply by 1.10:
12,823.75 x 1.10 = 14,106.13
List price = $14,106.13

Graph the function and its parent function. Then describe the transformation. f(x) = x + 3
Please Help ASAP
We have graphed the function f(x) = x + 3 and it's parent function f(x) = x in the image attached below and the parent graph has been transformed 3 units up onto the y axis.
What is a function ?A function is a set of outputs for some set of inputs we can graph function s in x-y co-ordinate.
According to the given question we have to graph a function and it's parent function.
We know a parent function is a function which is free from any transformation so parent function of f(x) = x + 3 is f(x) = x.
f(x) = x implies y = x.
Some points are (-5,-5), (0,0), (2,2).
Graph of these function is attached in the image below.
f(x) = x + 3 here when x = 0 y = 3 implies the whole graph has been transformed 3 units up onto the y axis.
Image of this transformed graph has also been attached.
